Review on 🌬️ AC Infinity AIRTITAN T8-N: Ultimate Crawlspace Basement Ventilator Fan with Temperature and Dehumidistat - IP-44 Rated Intake Solution by Wendy Key

I bought this fan for my mother's greenhouse less than 1 month ago, when I got the fan I plugged it in and it turned on and worked fine. When my mum got back from holiday I went to plug in the fan and show her and the menu on the display barely lit up and you couldn't see the controls, sometimes it lit up enough to see but then some of which keys would light up. doesn't work, I called support and they hung up, I'm very dissatisfied
